The "IS200" prefix identifies the board as a GE Industrial Control Systems product, with "200" specifically indicating that the board is a base-level assembly. The "STAI" acronym identifies the board's functional designation as a Simplex Analog Input Terminal Board. The "H2" designation identifies the hardware group and the plug-in terminal block configuration, while the "ABA" suffix identifies the artwork and functional revision combination. All digits are important when ordering or replacing any board, as boards of different revision levels may not contain identical hardware, and GE ensures backward compatibility of replacement boards while noting that different revision levels may not contain identical components.
The IS200STAIH2ABA Simplex Analog Input Terminal Board uses high-density Euro-style box terminal blocks and includes an onboard ID chip that identifies the board to the I/O pack for system diagnostic purposes. The board revision determines compatibility with the Mark VIe PAIC and YAIC controllers: the STAIH2A variant is compatible with the Mark VIe PAIC and uses plug-in terminals, while other STAI revisions offer fixed terminals, IEC 61508 safety certification with the YAIC, or no terminal block for direct soldering. The IS200STAIH2ABA Simplex Analog Input Terminal Board is therefore part of a versatile terminal board family that can be matched to the specific controller, safety, and wiring requirements of each application.
This product introduction provides detailed technical information, functional descriptions, connector assignments, configuration guidance, and comprehensive specifications for the GE IS200STAIH2ABA Simplex Analog Input Terminal Board, serving as an essential reference for control system engineers, maintenance technicians, and system integrators working with GE industrial control equipment.
Functional Architecture and Signal Processing
The IS200STAIH2ABA Simplex Analog Input Terminal Board is built around a flexible analog signal conditioning architecture that supports multiple input types and ranges across ten analog input channels and two analog output channels. This architecture allows the board to interface with a wide variety of field instruments while providing the isolation, filtering, and scaling required for accurate measurement in industrial environments.
The ten analog inputs of the IS200STAIH2ABA Simplex Analog Input Terminal Board accommodate two-wire, three-wire, four-wire, or externally powered transmitters. Inputs 1 through 8 support ±5 V DC, ±10 V DC, or 4–20 mA signals, while inputs 9 and 10 support 4–20 mA or ±1 mA signals, providing a dedicated low-current range for specialized transmitters. The input accuracy is ±0.1% of full scale over the full operating temperature range, and the maximum lead resistance is 15 ohms two-way with a cable length of up to 300 meters (984 feet), ensuring accurate measurement even with long field wiring runs.
The two analog outputs of the IS200STAIH2ABA Simplex Analog Input Terminal Board are 0–20 mA current outputs. Only with the Mark VIe PAICH2 controller can one analog output jumper be configured to 0–200 mA current, providing a higher-current output for specialized loads. The 200 mA output is not supported by the Mark VIeS YAIC controller, so the output configuration must be matched to the controller in use. The load on the output currents is 800 ohms maximum burden for the 4–20 mA output, and 50 ohms maximum burden for the 200 mA output when using the Mark VIe PAICH2.
The board provides 24 V DC power on the terminal board for all the transmitters, eliminating the need for separate field power supplies for most two-wire transmitters. The choice of current or voltage inputs is made using jumpers, allowing each channel to be configured independently to match the connected transmitter. The onboard ID chip identifies the board to the I/O pack, enabling system diagnostics and configuration validation.
Installation and Wiring
The IS200STAIH2ABA Simplex Analog Input Terminal Board is designed for flexible installation in standard industrial cabinets. The board plus a plastic insulator mounts on a sheet metal carrier that then mounts on a DIN-rail, or optionally the board plus insulator mounts on a sheet metal assembly and then bolts directly to a cabinet. This dual mounting approach allows the board to be installed in a wide range of cabinet arrangements.
The IS200STAIH2ABA Simplex Analog Input Terminal Board has a right-angle header accepting a range of commercially available pluggable Euro-style terminal blocks, with a total of 48 terminals. This pluggable terminal block configuration simplifies field wiring and maintenance, allowing the terminal blocks to be removed for wiring and then plugged back into the board. Typically, #18 AWG wires (shielded twisted pair) are used, and an I/O cable shield terminal is provided adjacent to the terminal blocks to ensure proper shielding and grounding of the analog signal cables.
The board accommodates the following types of analog inputs and outputs: analog input from two-wire transmitters, three-wire transmitters, four-wire transmitters, and externally powered transmitters; analog input for voltage ±5 V DC and ±10 V DC; analog input for current 4–20 mA; two analog outputs of 0–20 mA current; and, only with the Mark VIe PAICH2, one analog output of 0–200 mA current. The wiring, jumper positions, and cable connections are displayed on the wiring diagram, which should be consulted during installation to ensure correct configuration.
Jumper Configuration
The IS200STAIH2ABA Simplex Analog Input Terminal Board is configured by jumpers, which allow each input and output channel to be matched to the specific field device and application requirements.
Jumpers JP1A through JP8A select either current input or voltage input for inputs 1 through 8. Jumpers JP1B through JP8B select whether the return is connected to common or is left open for inputs 1 through 8. Jumpers JP9A and JP10A select either 1 mA or 20 mA input current for inputs 9 and 10, and jumpers JP9B and JP10B select whether the return is connected to common or is left open for these two channels. Jumper JP0 sets output 1 to either 20 mA or 0–200 mA, with the 200 mA setting available only with the Mark VIe PAICH2.
The jumper settings must be verified against the wiring diagram and the specific field transmitter requirements before the board is placed in service. Incorrect jumper settings can result in inaccurate readings, out-of-range signals, or damage to the connected equipment.
Diagnostics and Board Identification
The IS200STAIH2ABA Simplex Analog Input Terminal Board provides comprehensive diagnostic capabilities that assist with system verification and fault isolation. The board provides the voltage drop across a series resistor to indicate the output current, allowing the I/O pack to monitor the output current and detect unhealthy conditions. The I/O pack creates a diagnostic alarm (fault) if any one of the eight outputs goes unhealthy, alerting the operator to a potential problem with the field wiring or the connected device.
Each cable connector on the terminal board has its own ID device that is interrogated by the I/O pack. The ID device is a read-only chip coded with the terminal board serial number, board type, revision number, and the JR, JS, or JT connector location. When this chip is read by the I/O pack and a mismatch is encountered, a hardware incompatibility fault is created, preventing the system from operating with incorrect or mismatched hardware. This diagnostic feature ensures that the correct terminal board is installed in each location and that the system configuration matches the physical hardware.
Application Suitability and System Integration
The IS200STAIH2ABA Simplex Analog Input Terminal Board is a versatile analog interface that can be used in a wide variety of GE Industrial Control System applications. Its ten analog inputs, supporting two-wire, three-wire, four-wire, and externally powered transmitters across voltage and current ranges, allow the board to interface with pressure transmitters, temperature transmitters, flow meters, level sensors, and many other analog field instruments. Its two analog outputs provide 0–20 mA or 4–20 mA current signals for valve positioners, actuators, recorders, and other analog loads, with the optional 0–200 mA output available for higher-current applications when used with the Mark VIe PAICH2.
In Mark VIe controller applications, the IS200STAIH2ABA Simplex Analog Input Terminal Board serves as the field-side termination point for the analog channels, with the I/O pack connecting to the board to acquire the analog signals and communicate with the controller over Ethernet. The board's pluggable terminal block configuration simplifies field wiring, and the onboard ID chip ensures that the correct terminal board is installed in each location and that the system configuration matches the physical hardware.
The board's DIN-rail mounting and sheet metal carrier simplify installation in standard control cabinets, and the optional direct cabinet bolt-on mounting provides additional flexibility for different cabinet arrangements. The comprehensive jumper configuration allows each input and output channel to be matched to the specific field device, ensuring accurate measurement and reliable control even in electrically noisy industrial environments.
Maintenance and Lifecycle
The IS200STAIH2ABA Simplex Analog Input Terminal Board is designed for long service life with minimal maintenance. The board contains no moving parts, and its surface-mount construction ensures high reliability in continuous industrial operation. Routine maintenance consists of periodic visual inspection of the board, terminal blocks, and wiring, verification that the jumpers are set correctly for each channel, and confirmation that the shield terminals are properly connected.
The board's diagnostic features, including the output current monitoring and the onboard ID chip, simplify troubleshooting and ensure that the correct board is installed in each location. If an output becomes unhealthy, the I/O pack generates a diagnostic alarm, alerting the operator to a potential problem with the field wiring or the connected device.
If the board requires replacement, the process is straightforward. After de-energizing the associated equipment and verifying that no power exists, the pluggable terminal blocks should be labeled and removed, and the board should be removed from its mounting. The replacement board should be installed in the same position, the jumpers set to match the original configuration, and the terminal blocks reconnected as labeled before returning the system to service.
GE Industrial Control Systems ensures compatibility of its replacement boards, even though boards of different revision levels may not contain identical hardware. When ordering a replacement IS200STAIH2ABA Simplex Analog Input Terminal Board, provide the complete part number and description, the drive or system serial number, and the Material List (ML) number.
